--- Comment #1 from Basile-z <b2.temp at gmx.com> ---
looks fixed in 2.089.0, but a reduced case shows it's definitevely not:


---
module still;

template Foo() {
    unittest {}
}

void bar()
{
    __traits(getUnitTests, Foo);
}  
---


2.089 emits an error when trying to get the test for bar, while the segfault is
for the template.
